Were you aware that there is a pyramid in the heavens, or in the stars? It is located in the constellation of Libra, The Scales, whose ancient name was The Altar (according to "The Witness of the Stars" by E.W. Bullinger). This is very interesting because the Great Pyramid is called an altar in our heavenly Father's Word, in the book of Isaiah, chapter 19:
19 In that day shall there be an altar to the LORD in the midst of the land of Egypt, and a pillar at the border thereof to the LORD. 20 And it shall be for a sign and for a witness unto the LORD of hosts in the land of Egypt: for they shall cry unto the LORD because of the oppressors, and He shall send them a Saviour, and a great One, and He shall deliver them.
The following image shows what the heavenly altar looks like on a pictorial star chart. These constellations are most easily seen (from my latitude of 55 degrees north) looking southward in the early mornings of February to April.
To the right of this pyramid are the constellations of Virgo and Leo which, when combined, form a Sphinx.
I believe the Sphinx is the pillar that is referred to in Isaiah 19:19 because it is made from one stone whereas the Great Pyramid is many stones like an altar.
The pyramid in the stars is actually created from the constellations Libra (the Scales) and Ophiuchus (the Serpent Holder). Libra takes up the 2 stars at lower right, and the other 5 belong to Ophiuchus, for a total of 7. Below the pyramid is Scorpio, and its brightest star Antares. This constellation corresponds to the pit under the Great Pyramid. Above the pyramid is Serpens Caput (the Serpent's Head). It is poised to go after Corona Borealis (the Northern Crown) which I believe represents the capstone. Here's a more detailed look:
Look for the reddish star Arcturus as you search the sky. It's the easiest to find. Also very easy to see is Virgo's brightest star, Spica (or Al Zimach).
There is an actual photograph of the pyramid above Mt. Etna at the Astronomy Picture of the Day. Look for reddish Antares just above and to the left of the lava plume, and turn your head slightly to the left to see the pyramid.
